What does ENTEK do?
ENTEK sells lead-acid separators, lithium-ion separators, extruders, and engineering services on six continents. We design and build our battery separator lines, extruders, and parts with our in-house engineering, machining, and fabrication resources.
What is a battery separator?
A separator is a porous membrane placed between electrodes of opposite polarity, permeable to ionic flow but preventing electric contact of the electrodes. A variety of separators have been used in batteries over the years.
What are lead-acid battery separators made of?
A separator for a lead-acid battery comprising a porous membrane made mainly from a polyolefin resin, an inorganic powder and a mineral oil and containing a surface active agent as an auxiliary material, characterized in that the amount of any reducing substance liberated or eluted after 24 hours of electrolysis …
Who is Entek?

What is the difference between wet and gel batteries?
A gel battery (also known as a “gel cell”) is a VRLA battery with a ‘gelified’ electrolyte. Unlike a flooded wet-cell lead-acid battery, these batteries do not need to be kept upright. Chemically they are the same as wet (non-sealed) batteries except that the antimony in the lead plates is replaced by calcium.
What power supply is needed to charge a lead acid battery?
To charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage.
What is the purpose of separator in a lead acid battery?
The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.
Is a wet battery AGM?
Wet cell (flooded), gel cell, and absorbed glass mat (AGM) are various versions of the lead acid battery. The wet cell comes in two styles; serviceable and maintenance free. Both are filled with electrolyte and are basically the same. Gel cell and some AGM batteries may require a special charging rate.
What happens if you charge a battery with too much voltage?
As a result of too high a charge voltage excessive current will flow into the battery, after reaching full charge, causing decomposition of water in the electrolyte and premature aging. At high rates of overcharge a battery will progressively heat up.
Can I use lead acid battery while charging?
When the charger is charging, the charger is providing the power to the radio and some more power to the battery. You can not possibly use battery power while the charger is operating. The current will not go into the battery and then come back out of the battery to run the radio.
